<h2>Storm tracks data</h2>

<h3>Description</h3>

<p>This data is a subset of the NOAA Atlantic hurricane database best track
data, <a href="http://www.nhc.noaa.gov/data/#hurdat">http://www.nhc.noaa.gov/data/#hurdat</a>. The data includes the
positions and attributes of 198 tropical storms, measured every six hours
during the lifetime of a storm.
